Background

The set of standards and accompanying technical reports on the energy performance of buildings (set of EPB standards) have been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association (Mandate M/480), to support the EPBD.

The EPBD, the European Directive 2010/31/EU recasting the Directive 2002/91/EC on energy performance of buildings promotes the improvement of the energy performance of buildings within the European Union, taking into account all types of energy uses (heating, domestic hot water, lighting, cooling, air conditioning, ventilation) and outdoor climatic and local conditions, as well as indoor climate requirements and cost effectiveness (Article 1).

The mandate M/480 was issued as the recast of the EPBD raised the need to revisit already existing standards and reformulate and add standards so that they become on the one hand unambiguous and compatible, and on the other hand a clear and explicit overview of the choices, boundary conditions and input data that need to be defined at national or regional level.

Such national or regional choices remain necessary, due to differences in climate, culture & building tradition, policy and legal frameworks.

The development of the set of EPB standards was not restricted to Europe. For instance the main EPB standard, the EPB overarching standard EN ISO 52000-1, and the subset of EPB standards on building energy needs and building elements is done at global level, in a cooperation between CEN (Europe) and ISO (worldwide).

In general, the set of EPB standards were developed in five CEN Technical Committees (Europe), in two ISO Technical Committees (worldwide), each covering a specific expertise. The mandate M/480 project (2011-2016) enabled the required effective central coordination via the CTL (expert group of CEN core Team Leaders) of CEN/TC371 to obtain and secure consistency of the overall approach and of the technical details.
